TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Application filed October 1, 1890.

.To all whom it may concern:

are provided with both upper and lowercase types, or two or moreprinting surfaces or types; and it consists in the novel means wherebysaid types are enabled to act substantially as is hereinafter set forthand claimed, aided by the annexed drawings, making part of thisspecification, in which Figure 1 is a front elevation exhibiting asufficient portion of a type-writing machine for an understanding of thepresentimprove ment. Fig. 2 is a vertical longitudinal section on theline 2 2 of Fig. 1; Fig. 3, a view analogous to that of Fig. 2, butshowing the cam in its up position and not including all of the partsshown in Fig. 3; Fig. 4, aplan of the outer end of a type-bar, thetype-sleeve being slipped inward thereon; Fig. 5, a similar view of thetype-bar, the type-sleeve being slipped outward thereon; Fig. 6,a sideelevation of the outer end of a type-bar; the type-sleeve being slippedinward thereon; and Fig. 7 a cross-section of the type-bar and sleeve.The last four-named views are upon an enlarged scale.

The same letters of reference denote the same parts.

In carrying out this improvement I desire not to be restricted to anyspecial form of type-writing machines, as there are several forms ofsuch machines to which the improvement is applicable. One such form isillustrated in the accompanying drawings, and will be presentlydescribed in part. In typewriting machines of the class referred to ashitherto made the types are enabled to act, re-

spectively,by means of an adjustable platen, the platen being in oneposition for the lowercase types to act and being shifted into anotherposition for the upper-case types to act; and in other machines thetype-bars are respectively provided with type-blocks having types uponopposite sides thereof and which are respectively brought into positionfor use by Patent No. 474,533, dated May 10, 1892.

type-bar. In the machine under consideration this construction is asfollows: Each typebar is provided with a lower and also with an uppercase type or with any other types, and the types are adjustable withreference to the platenthat is, the two types upon each typebar aremovable upon the type-bar, so that either one of them at will can bebrought into position to coact with the platen.

A represents an ordinary platen of a typewriting machine. Only so muchof the platen and also of the machine is exhibited as is needed for anexplanation of the improvement.

B represents one of, the type-bars.

O and D respectively represent the upper and lower case types, withwhich the type-bar is provided. They are, as stated, attached to thetype-bar, so that they can be adjusted thereon to bring either of them,as desired, into position to act when the type-bar is op erated. To thisend the two types are attached to a sleeve E, which can he slippedlongitudinally upon the type-bar. The two positions of the type-sleeveare substantially indicated in Figs. 4 and 5, respectively. The type-baris provided with suitable shoulders I) and b to limit the movementof'the sleeve thereon. To enable it to be moved upon the washe flIl'ihstie mn I s stance coacts with a cam F. The cam is adjustable withreference to the platen to enable it to guide that one of the types 0 Dinto position for use, which for the time being it is desired to use. Tothis end, as the most desirable shape and movement therefor, the cam hastwo inclined surfaces f f which converge toward each other and lead to arecess f in the cam, and the cam is attached to a rod G, by means ofwhich the cam can be raised and lowered or adjusted with reference tothe platen A. The rod G is jointed to what is termed the upper-caselever H. This lever is adapted to be vibrated in a manner analogous tothat of an ordinary type-lever of the keyboard of a type-writingmachine, and so that the operator, whenever it is desired to use anupper-case type, can operate the lever and thereby suitably adjust thecam above described. In the present instance the turning the type-blockhalf-way round on the fulcrum of the lever H is shown at h, and theModem 2 Sheets-Sheet 1.
